Silicon Nitride Structural Components for Sand Mills
Product Overview
Silicon Nitride Structural Components are engineered specifically for sand mills and grinding equipment, serving as high-wear parts including liners and stirring discs. These components deliver exceptional wear resistance, corrosion resistance, and oxidation resistance while maintaining long-term stability under high-speed operation and particle impact conditions, significantly extending equipment service life and enhancing production efficiency.
Key Features
High-Temperature & Wear Resistance Adapts to high-speed operation and particle impact with minimal wear rate and extended service life
Excellent Oxidation Resistance Resists metal infiltration and corrosion, suitable for diverse media environments
High Hardness & Toughness Vickers hardness of 15-16GPa with superior impact resistance to minimize fracture risk
Strong Chemical Stability Resists acid and alkali corrosion while maintaining stable performance in humid or corrosive conditions
Typical Applications
  • Sand mill liners
  • Stirring discs and dispersion discs
  • High-wear grinding media accessories
